initial commit for google speech api plugin

will use libsprec/libjsonz for actual work
Fixed submodules
Plugin can load dynamic libraries

Libraries should use @library_path as install path.
basic implementation of patch

test file is sent to recognition service
debug pseudorecognition, which takes 4 seconds
use global concurrent queue instead of main queue

This queue will spawn new working threads
Recognition from mic
Begin to implement class for recording unspecified time of pseech

PublicUtility is from apple's CoreAudio Public Utility
Recording for the undefined time

It will be started at rising edge and stopped at the falling edge of the "Start" port value.
Little additional check
Proper stopping if recording got error and stopped by itself.
Do refactoring - almost all access to recorderUserData is protected with the stateCondition lock.
update libsprec submodule
Use flac encoder provided by libsprec

Although, it doesn't work now - it crashes somewhere inside libflac
Correct recording of the flac stream
Add test app
App will write recorded flac to file
Fix compilation errors due to ARC
Fix trashed sound
Record in mono
